and sixth planar faces. The first and second faces are generally
parallel, and the distance between the first and second faces
define a thickness of the first block; the third and fourth faces
are parallel to each other and perpendicular to the first and
second faces; the fifth face is perpendicular to the first, second,
third, and fourth faces; the sixth face: extends perpendicular to
the third face; extends toward the fourth face and ends at a
non-planar remainder section; is parallel to the fifth face; is
contained in a plane that intersects a plane containing the third
face; and a distance from the intersection to the remainder section
is at least as long as the thickness of the first block; and the
remainder section extends between the sixth face and the fourth
face and has a shape such that when a second block of the same
construction as the first block has its remainder section engaged
against the remainder section of first block, the remainder
sections of the first and second blocks mate.

DETAILED DESCRIPTION
[0061] A. Molded Concrete Blocks--Generally
[0062] While the techniques described herein were particularly
developed for use with concrete blocks made by a dry-cast process,
various ones of the techniques described can be applied to concrete
blocks formed by wet cast processes, concrete press processes,
concrete extrusion processes, 3D concrete printing processes, and
other processes.
[0063] The concrete blocks of particular interest here are
generally ones that are mass-produced, and are molded having at
least one face or face section molded into a configuration such
that the block can be used, together with other such blocks, to
create a structure that simulates a wall or wall section made from
stone masonry, i.e. to simulate the appearance of many discrete and
differentiated stone pieces secured to one another with mortar or
similar material. To facilitate this, the blocks are molded with a
face or face section that has: visually distinct section(s) with
features emulating stone pieces (false stone sections); and,
various grooves between those distinct sections that simulate the
appearance of joints and/or mortar sections between individual
stones (false joints), in spite of the blocks actually having an
integral structure and not comprising individual pieces. The blocks
can also have a face or face section with various other types of
topology to give a craggy appearance, or other types of
three-dimensional (positive/negative topology) features, molded in
to create a visually attractive appearance. Techniques applicable
to mold such blocks are known. In the context of dry-cast concrete
blocks, the molding techniques are described, for example, in U.S.
Pat. No. 8,128,851, incorporated herein by reference.
[0064] Herein, the terms "molded block", "molded block unit" and
variants thereof, are meant to refer to a single unitary molded
block structure, without specific regard to the method of
manufacture (other than molding having been used). The term
"dry-cast concrete block" and variants thereof, is meant to
specifically reference a block that has been made from a dry-cast
concrete process as opposed to a wet-cast concrete process.
[0065] B. Example Block Types and Features--FIGS. 1-6, 10-13, 18,
21 and 22
[0066] It is noted that a concrete block can be characterized by
its features "as made"--that is, as the block is oriented within
the mold and when removed from the "mold" on a standard dry-cast
production line--; or "as installed"--that is, as the block is
oriented when installed in a wall or other structure in use.
[0067] FIG. 1 generally indicates an example concrete block
constructed in accord with the present disclosure. The concrete
block 20 includes a first face 22 referenced herein as the "first
face, or a front, decorative, face" or by similar terms. This is
the face of the block 20 that, when the block is used to form a
structure such as a wall, decorative feature, or retaining wall,
primarily faces a viewer in front of the wall. It is also
preferably a face that is visually enhanced in accord with the
present techniques.
[0068] Opposite the first face 22 is a second face 24, which is
generally referred to herein alternatively as a "back or rear"
face. When the block 1 is made in a "dry-cast" mold process, it is
typically constructed with front face 22 being directed upwardly
and rear face 24 being a bottom surface or downwardly directed
surface. When removed from the mold, as a green block for
transportation to a curing station, the block is typically oriented
resting on the machine pallet with surface 24 down (against the
pallet) and face 22 up.
[0069] Blocks, such as block 20, generally include third and fourth
opposite faces 26, 28 that, in use in a wall or other structure,
are the left and right sides extending between the first face 22
and second face 24. The block 20 also includes a fifth (bottom)
face 30 and sixth (top or upper) face 32 each extending between
surfaces 22, 24 and surfaces 26, 28.
[0070] Still referring to FIG. 1, the first face 22 is decorative
and can be seen as having visually distinct false stone sections
22a, 22b, 22c, 22d and 22e separated by groove or false joint
sections 22f. These groove sections 22f are molded sections that
cause the appearance of the separate sections 22a-22e, to simulate
an appearance in the face 22 of a resulting construction from a
masonry process in which separate stones (the appearance of which
is created by the sections 22a-22e) are joined together by mortar
to form the resulting structure. Techniques for creating such
sections and grooves are described for example in such references
as U.S. Pat. No. 8,128,851.
[0071] Herein, visually distinct sections such as 22a-22e will
sometimes referred to as "false stone sections." By this term it is
not meant to be suggested that the sections are actually separate,
but rather they are sections that create the appearance of separate
stones having been used in the resulting wall or other structure.
Sections such as 22f will be sometimes referred to as "false mortar
sections" or "false joints." By such terms it is not meant that the
sections actually include mortar, but rather the molded sections
that create the appearance of mortar between the false stone
sections. The decorative face 22 can also have a face that does not
include the visually distinct false stone sections and/or false
joints; such alternative decorative faces 22 can be any of a
variety of appearances including non-limiting flat faces, bumpy
faces, or a combination of flat and bumpy faces with or without the
use of false joints.
[0072] It is noted that in some instances portions of the third and
fourth faces 26, 28 can be provided with molded decorative features
to facilitate the appearance of stone sections and/or mortar
sections around a corner. This may be particularly desirable in
blocks that are to be used as corner blocks in a wall or other
construction.
[0073] In FIG. 2, a schematic plan view of the block 20 is
depicted, with the first face 22 being shown, but without the
decorative nature of the face 22 depicted. When the block 20 is a
dry-cast block, generated in a mold and removed therefrom on a
pallet, in a typical dry-cast process, the first face 22 is
upwardly directed, i.e., as an upper ("as made") face in the
uncured or green block. However, when the block is used in a wall,
first face 22 is generally a lateral face, with sixth face/upper
face 32 directed upwardly and fifth face/bottom face 30 directed
downwardly. Since first face 22 is the decorative face, it is
generally oriented in the resulting wall or other structure toward
the viewer.
[0074] In FIG. 2, the block 20 is depicted having an outer
perimeter shape in which the third and fourth faces 26, 28 are
parallel; and the fifth (bottom) face 30 is perpendicular to the
third and fourth faces 26, 28. In general, the first face 22 is
generally parallel to the second face 24. That is, by "generally
parallel", it is meant that even though the first face 22 can be
decorative with false stone sections or other non-flat shapes, a
plane from which the decorative face projections project in the
first face 22 is parallel to the second face 24, and the distance
34 (FIG. 1) between the first face 22 and second face 24 defines
the thickness of the block 20.
[0075] The first face 22, second face 24, third face 26, fourth
face 28, fifth face 30, and sixth face 32 are planar faces. In this
context, the term "planar" means that the faces can have some
projections and/or recesses, but the overall visual impression is
generally planar in that most of the outermost projections are
contained within the same general plane. For example, even though
the first face 22 can be decorative with false stone sections, it
is considered planar since most of the outermost projections are
contained within the same plane.
[0076] Still in reference to FIG. 2, the sixth/upper face 32 has a
first section 36 that extends from and is perpendicular to the
third face 26. The first section 36 is parallel to the fifth
(bottom) face 30 and extends from the third face 26 toward the
fourth face 28 and ends at a remainder section 38. The remainder
section 38 is also referred to herein as an "irregular section 38",
as it can have a perimeter with an irregular shape. The first
section 36 has a length 40 from the third face 26 to the remainder
section 38 that is as least as long as the distance 34 defining the
thickness of the block 20. In many arrangements, the length 40 is
equal to the thickness. This relationship leads to advantages when
constructing structures (e.g. walls, columns, etc.) with corners,
as described further below.
[0077] The remainder section 38 extends between the first section
36 of the sixth face 32 and the fourth face 28 and is perpendicular
to the first (front) face 22 and second (back) face 24. The
perimeter surface of the remainder section 38 is shaped such that
when a second block of the same construction as the block 20 has
its remainder section 38 engaged against the remainder section 38
of the original block 20, the remainder sections 38 of the two
blocks mate or mateably engage one another.
[0078] Attention is directed to FIG. 18. FIG. 18 shows the block 20
of FIG. 1 in front plan view. The remainder section/irregular
section 38 can be seen extending from the first section 36 of the
top face 32. Also depicted in FIG. 18 is the broken line of a plane
at 46. The plane 46 is parallel to the fifth face/bottom 30 and
perpendicular to planes containing the third face 26 and fourth
face 28. The plane 46 contains within it (i.e., is co-planar with)
the first section 36 of the sixth/top face 32.
[0079] The remainder/irregular section 38 includes at least a first
cavity 48 that is recessed from the plane 46. The first cavity 48
forms a depression or recess from the plane 46 in a direction
toward the fifth face/bottom 30. While many different embodiments
are possible, in the example shown, the first cavity 48 has a
perimeter shape of a trapezoid 50. The parallel portions of the
trapezoid 50 include section 51 of the irregular section 38 of the
block 20 and the plane 46. Extending between the parallel section
51 and plane 46 are inclines or ramps 52, 53. The ramp is slanted
downward and away from the first section 36 ending at the section
51. The section 51 is generally parallel to the fifth face/bottom
30. The ramp 53 is slanted or angled upward and away from the
section 51 to the plane 46.
[0080] The remainder or irregular section 38 further includes at
least a first projection 54. The first projection 54 extends or
projects from the plane 46 in a direction away from the rest of the
block 20. The first projection 54 has a perimeter shape 55. The
perimeter shape 55 is the same shape as perimeter shape 50 of the
first cavity 48. In this example embodiment, the perimeter shape 55
of the first projection is trapezoidal, as described above with
respect to perimeter shape 50. The perimeter shape 55 in the form
of a trapezoid includes parallel section 56, which is parallel to
the fifth/bottom face 30 and the plane 46. It is also parallel to
the section 51 and section 36 along the top face 32. Extending
between parallel section 56 and plane 46 is ramp 57. Ramp 57 forms
a continuous planar surface with the ramp 53. Extending from the
parallel section 56 is ramp 58, which extends downward and away
from parallel section 56 to the fourth face 28.
[0081] Because of the shape of the irregular section 38, including
the symmetry between the perimeter shape 50 of first cavity 48 and
perimeter shape 55 of the first projection 54, the block 20 can be
mateably engaged or fitted together with a second block 20 of the
same construction.
[0082] In other embodiments, as will be explained further below,
there can be additional cavities and projections along the
irregular section 38, and the perimeter shapes of the projections
and cavities can be alternatively shaped including polyhedral
shapes, curved shapes, and combinations of polyhedral and curved
shapes.
[0083] In FIG. 2, it can be seen how in this embodiment, the
remainder/irregular section 38 includes a plurality of planar faces
relative to each other at non-straight and non-zero angles. The
plurality of planar faces can include at least three planar faces,
and in the embodiment shown in FIG. 2, at least five planar faces.
In FIG. 2, the planar faces include, starting at the end of the
first section 36: ramp 52, parallel section 51, ramp 53 together
with ramp 57, parallel section 56, and ramp 58. Ramp 58 ends at
fourth face 28. In other embodiments, there can be more or fewer
faces in the remainder section 38, or the parts of the remainder
section can be curved.
[0084] The block 20 of FIG. 1 can be many different sizes and
shapes. In FIG. 2, example dimensions are indicated. An example
length of the block 20 from third face 26 to the fourth face 28
shown at reference numeral 60 is at least 10 inches, not greater
than 20 inches, and about 14 inches. The distance 60a from the
third face 26 to the section 51 is about 5-6 inches, while the
distance 60b between the fourth face 28 to the section 51 is
greater than 60a, at about 6-7 inches. The height of the block 20
at 61 between the bottom face 30 and first section 36 of the top
face 32 is at least 5 inches, no greater than 15 inches, and in one
example about 9 inches. The height 62 between the bottom face 30
and section 56 of the first projection 54 is at least 6 inches, no
greater than 16 inches, and in one example about 10-11 inches. The
thickness 34 shown in FIG. 1, which is the same as length 40 of the
first section 36 of the top face 32 is at least 3 inches, no
greater than 10 inches, and in one example about 4 inches. The
depth of the first cavity 48 shown at 62 is at least 0.5 inch, no
greater than 3 inches, and one example about 1-2 inches. The depth
63 is the same as the height of the first projection 54. The
distance 64 along the plane 46 from where the first section 36 ends
to where the plane 46 intersects the end of the ramp 53 and the
beginning of the ramp 57 is at least 3 inches, no greater than 7
inches, and in one example about 5 inches. This distance 64 is also
the same as distance 65, which is the distance of the plane 46 from
where the ramp 53 ends and ramp 57 begins to where the ramp 58 ends
at the fourth face 28. A length 66 of the section 51 between ramps
52 and 53 is at least 0.5 inch, no greater than three inches, and
in one example about 1 inch.
[0085] FIG. 3 illustrates the blocks 20 as laid out on a pallet,
for example after molding and curing. The blocks 20 are shown as
they would be arranged on the pallet, resting on their back faces
24 with the front faces 22 facing upward. In this example, the
pallet has a size of about 42 inches by 36 inches and holds four
rows of 3 blocks 20 each.
[0086] It can be see how the bottom row 68 of blocks 20 are
arranged end to end, with the fourth face 28 against the third face
26 of the next adjacent block. In the second row 69, the blocks 20
are also end to end, but the remainder sections 38 of the blocks 20
in the second row are engaged against the remainder sections of 38
of the first row. The projections 54 in the remainder sections 38
of the first row 68. The third row 70 is shown oriented in the same
configuration as the first row 68, and the fifth face/bottom 30 of
the blocks 20 in the third row 70 are against the bottoms 30 of the
second row 69. The fourth row 70 is oriented in the same way as the
second row 69, with the remainder sections 38 of the fourth row 71
mateably engaging the remainder sections 38 of the third row
70.
[0087] FIG. 4 is a front plan view of four of the blocks 20 mated
together. As can be seen, the shape of the remainder
section/irregular section 38 is such that when block 20 of the same
construction has its remainder section/irregular section 38 engaged
against the remainder section/irregular section 38 of the first
block, the two remainder sections 38 mateably engage. By mateably
engaged, in this example, it means that the first projection 54 of
the blocks 20 in the upper layer are received by the first cavities
48 of the blocks 20 in the lower layer; and the first projections
54 of the blocks 20 in the lower layer are received by the first
cavities 48 of the blocks 20 in the upper layer. The first section
36 of the sixth face 32 of the end block 74 in the bottom layer is
open and exposed. It is available for receiving a block 20 in the
upper layer either oriented 90.degree. to it, to form a corner, or
straight alongside, to form another length in the wall. Because the
length 40 of the first section 36 is the same as the thickness 34
of the block 20, the block 20 is advantageously shaped for forming
corners.
[0088] FIGS. 5 and 6 show some example structures that can be made
from the block 20. A variety of structures are possible including
free standing walls, walls with inside and outside corners,
benches, garden walls, planters, tables, bars, fencing, columns,
outdoor living areas, mailbox inserts, fire pits, benches with
columns, planters and columns, decking over short columns, etc. In
FIG. 5 is a construction 76 made from the blocks 20 having three
columns 77, 78, 79. A pair of parallel facing walls extend between
columns 77 and 78, and between the walls is a section 80 which can
hold plants. A pair of parallel walls capped with cap blocks 82
extend between columns 78 and 79, and can form a seating area.
[0089] In FIG. 6, is a back-to-back wall 84 between two columns 85,
86. Each of the columns 85, 86 and wall 84 are constructed from the
blocks 20.
[0090] In reference to FIG. 5, the construction 76 includes the
planted section 80, which is a pair of parallel facing walls, one
of which is shown at 88. In between the walls 88 plants may be
placed. The wall 88 is constructed by forming a base course/layer
90 along the ground, with the blocks 20 arranged side by side, such
that the first faces 22 of the blocks 20 are generally co-planar,
the fifth face 30 is against the ground, and the sixth face 32 with
the remainder section 38 is facing up. A first course/layer 91 of
the blocks 20 (referred to herein as "second blocks 20) are stacked
on the base course 90 so that the sixth face 32 of most of the
second blocks 20 in the first course 91 are engaged against the
sixth face 32 of the blocks 20 in the base course 90. The remainder
section 38 of most of the second blocks 20 is in mating engagement
with the remainder section 38 of the blocks in the base course
90.
[0091] Still in reference to FIG. 5, the construction 76 has a
corner 77, in which there is a second wall section 94 perpendicular
to the wall 88. The second wall section 94 has a base course 95 of
the blocks 20 arranged side by side such that the first faces 22 of
the blocks 20 in the second wall section 94 are generally co-planar
and perpendicular to a plane containing the first faces 22 of the
wall 88.
[0092] The second wall section 94 has a first course 96 of the
blocks 20 (called "second blocks 20") stacked on the second wall
section 94 base layer 95 so that the sixth face 32 of most of the
second blocks 20 in the second wall section 94 is engaged against
the sixth face 32 of the first blocks 20 in the base layer 95 of
the second wall section 94, and the remainder section 38 of most of
the second blocks 20 in the second wall section 94 is in mating
engagement with the remainder section 38 of the blocks 20 in the
base layer 95 of the second wall section 94. The sixth face 32 of
one of the blocks 20 at a first end 98 of the second wall section
94 first layer 96 is engaged against the sixth face 32 of one of
the blocks 20 at the first end 98 of the base layer 90 of the first
wall section 88.
[0093] In the embodiment of FIG. 5, the wall sections 88 and 94 are
shown as having only a base course and first course of the blocks
20, but in other embodiments, there can be further layers, as
further shown in FIG. 10, described below. The columns 77, 78, and
79 have two additional courses arranged in the same manner as the
base course and first course.
[0094] In FIG. 6, the back-to-back wall 84 is constructed like the
wall 88 of FIG. 5, except that there is no space between the
parallel walls; rather the parallel walls 101, 102 are engaged
back-to-back between the columns 85, 86.
[0095] FIG. 10 is the front view of a wall section 114 that can be
constructed of the blocks 20. In the embodiment of FIG. 10, there
are six layers of the blocks 20, shown at courses or layers 115,
116, 117, 118, 119, and 120.
[0096] FIG. 11 is another wall section 122 constructed with the
blocks 20. The difference between wall section 122 and wall section
114 is the existence of seams in the wall section 114. In the wall
section 114, there are seams 123, 124 between every two layers of
the wall section 114. For example, there is a seam 123 between
layer 116 and 117, and there is a seam 124 between layers 118, and
119. In the wall section of 122 of FIG. 11, there are no seams.
This is because the wall section 122 is made with the blocks 20 in
addition to the use of body pieces 126 (FIGS. 12, 13, 21 and 22).
In FIG. 11, the perimeters of some of the blocks 20 and body pieces
126 are bolded so that they can be more easily seen.
[0097] In FIGS. 12, 13, 21, and 22, the body piece 126 includes
first and second faces 127, 128. The faces 127, 128 are parallel
and can be generally planar. By "generally planar," it is meant
that any crags, indents, projections, or cavities, do not project
or recess greatly, such as no more than 1 inch.
[0098] In FIG. 21, the first face 127 is shown to have false joint
lines 130, dividing the first face 127 into visually distinct false
sections 127a, 127b, 127c, 127d, 127e, 127f, and 127g. These false
stone sections 127a-127g are separated by the false joint lines 130
to cause the appearance of separate sections 127a-127g, to simulate
an appearance in the face 127 of a resulting construction from a
masonry process in which separate stones are joined together by
mortar to form the resulting structure.
[0099] The distance between the first and second faces 127, 128,
defines the thickness of the body piece 126. The body piece 126
further includes third and fourth planar side faces 132, 133 that
are parallel to each other and perpendicular to the first end
second faces 127, 128.
[0100] Fifth and sixth faces 134, 135 are opposite to each other.
The first and second faces 127, 128 and third and fourth faces 132,
133 extend between the fifth and sixth faces 134, 135. Each of the
fifth and sixth faces 134, 135 have an identical profile shape to
each other. The profile shape for each of the faces 134, 135 is
described below using the same reference numbers.
[0101] In the example embodiment, the profile shape of faces 134,
135 includes at least a planar section 138 and a non-planar
remainder section 139. The planar section 138 extends from fourth
side face 133 and extends perpendicular to side face 133 toward the
third side face 132 ending at the remainder section 139.
[0102] The planar section 138 has a length that is as least as long
as the thickness of the first body piece 126, and can be equal to
the thickness. The non-planar remainder section 139 is formed such
that when a second body piece 126 of the same construction has its
non-planar remainder section 139 engaged against the non-planar
remainder section 139 of the first body piece 126, the
non-remainder sections 139 of the first and second body pieces 126
mateably engage.
[0103] In the example shown, which is designed for use with blocks
20, the non-planar remainder section 139 of the body piece 126
includes a plurality of planar faces/surfaces angled relative to
each other to form ramps at non-straight and non-zero angles. There
can be at least three planar faces, and in the example shown in
FIG. 12, there are five ramps 141, 142, 143, 144, 145. Still in
reference to FIG. 12, the non-planar remainder section 139 of each
of the fifth and sixth faces 134, 135 includes a first cavity 146
and a first projection 147. The first cavity 146 is recessed from a
plane 148 that is co-planar with the planar section 138, and the
first cavity 146 is recessed in a direction toward the opposite
face. That is, in the fifth face 134, the first cavity 146 is
recessed toward the sixth face 135, while in the sixth face 135,
the first cavity 146 is recessed toward the fifth face 134.
[0104] The first projection 147 extends from the plane 148 that is
co-planar with the planar section 138 in a direction away from a
remainder of the body piece 126. Each of the first cavity 146 and
first projection 147 have the same perimeter shape. In the example
shown in FIG. 12, the perimeter shape is a trapezoid. The trapezoid
of the first cavity 146 is defined by ramps 141, 142, and a portion
of 143. The trapezoid of the first projection 147 is defined by
ramps 144, 145, and a remainder of 143 that projects from the plane
148.
[0105] FIG. 13 shows the perimeter outline of body piece 126 with
example dimensions. A length of the body piece 126 between the
third face 132 and fourth face 133 is shown at 155 and can be at
least 10 inches, no greater than 20 inches, and about 13-15 inches.
The lengths 155a, 155b of the projection 147 and recess 146
respectively are at least 3 inches, no more than 7 inches, and
typically about 4-6 inches. The length 155c of the planar section
138 will often be less than the lengths of 155a and 155b, and will
be at least 2 inches, no more than 6 inches, and typically about
3-5 inches. A greatest height 156 of the body piece 126 between the
peaks of the projections 147 is at least 8 inches, no greater than
22 inches, and typically about 11-12 inches. A height 157 between
the planar sections is at least 6 inches, no greater than 12
inches, and typically about 8-10 inches. The thickness 158 (FIG.
22) of the body piece 126 will be as least as long as the length
155c of the planar section 138 and may be equal to the length 155c
in preferred arrangements. Many alternatives are possible.
[0106] Turning again to the wall section 122 of FIG. 11, it can be
seen how the wall section 122 includes base course/layer 150 of the
blocks 20 arranged side by side, such that the first faces 22 are
generally co-planar. Stacked on top of the base course 150 is a
first course 151 of the body pieces 126. The body pieces are
stacked on the base course 150 so that the planar section 138 of
the sixth surface 135 of each of the body pieces 126 in the first
course 151 is engaged against the sixth face 32 of the blocks 20 in
the base course 150. The non-planar remainder section 139 of the
sixth surface 135 of the first course 151 of body pieces 126 is in
mating engagement with the remainder section 38 of the sixth face
32 of the base course 150 of the blocks 20'.
[0107] A second course 152 of the body pieces 126 is stacked on the
first course 151 so that the planar section 138 of the fifth
surface 134 of each of the body pieces 126 in the second course 152
is engaged against the planar section 138 of the fifth surface 134
of the body pieces 126 in the first course 151. The non-planar
remainder section 139 of the fifth surface 134 of the second course
152 of body pieces 126 is in mating engagement with the non-planar
remainder section 139 of the fifth surface 134 of the first course
151 of body pieces 126.
[0108] Still in reference to FIG. 11, the wall section 122 further
includes a third course 154 of the blocks 20 stacked on the second
course 152 of body pieces 126 so that the sixth face 32 of each of
the blocks 20 in the third course 154 is engaged against the planar
section 138 of the sixth surface 135 of the body pieces 126 in the
second course 152. The remainder section 38 of the third course 154
of the blocks 20' is in mating engagement with the non-remainder
section 139 of the sixth surface 135 of the second course 152 of
body pieces 126.
[0109] It should be understood that body pieces 126 can be shaped
to work with the blocks 20 of any of the various embodiments
described herein and other variations within the scope of this
disclosure.
[0110] C. Example Block Type and Features, FIGS. 7-9
[0111] FIG. 7 illustrates another embodiment of the block, shown
here as block 20'. The same reference numerals are used for the
same parts, although it should be understood that the outer
perimeter has a different shape from that of the block of FIG. 1,
as further described.
[0112] In this embodiment, the first cavity 48 has a perimeter
shape of a triangle 110. The first projection 54 has a perimeter
shape of a triangle 112. The remainder/irregular section 38 has,
from left to right starting at the first section 36 of the sixth
face 32: ramp 104 extending downward and away from the first
section 36; ramp 105 extending upward and away from ramp 104; ramp
106 which is continuous with ramp 105; and ramp 107 extending
downward and away from ramp 106 to end at fourth face 28. The first
cavity 48 is defined by ramps 104, 105. The first projection 54 is
defined by ramps 106, 107.
[0113] In FIG. 8, the dimensions of the block 20' are illustrated.
The dimensions are about the same as the dimensions shown in the
FIG. 2 embodiment.
[0114] In FIG. 9, the blocks 20' are illustrated as they would be
laid out on a pallet, laying on their backs 24 with the first face
22 facing up. The pallet can accommodate four layers of three
blocks 20' each. It can be seen how the remainder sections 38
mateably engage each other.
[0115] D. Example Block Types FIGS. 14, 15, and 19
[0116] FIG. 14 illustrates another embodiment of the block, shown
here as block 20''. The same reference numerals are used for the
same parts, although it should be understood that the outer
perimeter of block 20'' has a different shape from that of the
block 20 of FIG. 1 and block 20' of FIG. 7, as further
described.
[0117] In this embodiment, the remainder section 38 includes seven
planar faces 161, 162, 163, 164, 165, 166, and 167. In FIG. 19, it
can be seen how the remainder/irregular section 38 has first cavity
48 with a perimeter shape of a triangle 170, while the first
projection 54 also includes a triangle perimeter shape 171.
[0118] The block 20'' further includes a second cavity 174. The
second cavity 174 is recessed in a direction toward the fifth face
30. There is a second projection 175 extending in a direction away
from the rest of the block 20''. The second cavity 174 and the
second projection 175 have the same perimeter shape. In this
example, the perimeter shape of the second cavity 174 and second
projection 175 is trapezoidal.
[0119] The planar faces 161, 162 are angled relative to each other
to form the first cavity 48. The planar faces 162, 163, and 164
form the trapezoidal shape of the second projection 175. The planar
faces of 164, 165, and 166 form the trapezoid of the second cavity
174. The planar faces 166 and 167 form the perimeter shape of the
first projection 54.
[0120] As can be seen in FIG. 14, the second projection 175 is
between the first cavity 48 and the second cavity 174. Furthermore,
the first cavity 48 and second cavity 174 alternate with the second
projection 175 and first projection 54 along the irregular section
38.
[0121] FIG. 15 shows a wall construction 178, including wall
section 178a and wall section 178b joined at a corner 180 assembled
from the blocks 20''. In the example shown in FIG. 15, the wall
construction 178 has four layers or courses of blocks 20''. It can
be seen how the base course 181 is laid with the fifth/bottom face
30 against the ground surface, and the first course 182 is
assembled on top of the base course 181 with the sixth face 32
pointed downwardly to mateably engage with the base course 181. The
remainder sections 38 of the blocks 20'' mateably engage with each
other.
[0122] The second course 183 is assembled with its fifth
face/bottom face 30 engaged against the fifth face/bottom 30 of the
first course 182. The third course 184 is assembled on top of the
second course 183 with the fifth face 30 pointed downwardly so that
the remainder sections 38 mateably engage between the second course
183 and third course 184.
[0123] At the corner 180, one of the blocks 20''a at the corner 180
is in the base course in part of the wall construction 178a and is
perpendicular to the wall construction 178b. The block 20''a has
its sixth face 32 engaged against the sixth face 32 of block 20''b
in the first course 182 in the wall construction 178b. A similar
construction of the corner 180 is made between the second course
183 and third course 184.
[0124] E. Example Block Types, FIGS. 16, 17, and 20
[0125] FIGS. 16, 17, and 20 illustrate another embodiment of the
block shown here as block 220. The same reference numerals are used
for the same parts, although it should be understood that the outer
perimeter of block 220 has a different shape from that of the block
20 of FIG. 1, as further described.
[0126] In the previous embodiments, in general, the shape of the
remainder section/irregular section 38 is polyhedral. In contrast,
in the embodiment of FIGS. 16, 17, and 20, the perimeter shape of
the remainder section 38 is curved. Some embodiments can also
include a combination of both polyhedral and curved shapes for the
remainder section 38.
[0127] In FIG. 16, the first cavity 48 has a perimeter that is
curved, while the first projection 54 has the same shape, which is
curved. The curved section of the first cavity 48 is defined by at
least one concavely curved surface 222, while the first projection
54 is defined by at least one convexly curved surface 224.
[0128] Many different perimeter shapes are possible, and in the
example shown, the first cavity 48 and first projection 54 are
generally in the shape of semi-circles. Other shapes can includes
sine-wave shapes, or any of a variety of shapes. There can be
multiple curved surfaces resulting in multiple cavities and
projections.
[0129] In FIG. 16, example dimensions are shown and many variations
are possible. The thickness of the block 220 is shown at 240 and
will be as least as long as the length 241 of the first section 36,
preferably equal to the length 241, with a value of at least 4
inches, no greater than 10 inches, and typically about 5-7 inches
or about 6 inches. The length 243 of the recess 48 and length 242
of the projection 54 will be equal and at least 6 inches, no
greater than 12 inches, and typically about 8-10 inches or about 9
inches. The depth 243 of the recess 48 and the height 244 of the
projection 54 will be equal and at least 2 inches, no greater than
8 inches, typically about 3-5 inches or about 4 inches.
[0130] In FIG. 17 is a wall construction 226 made from the blocks
220. The wall construction includes a first segment 226a and a
second segment 226b joined at a corner 228.
[0131] The wall construction 226 has two courses, shown as base
course 230, which is against the ground and first course or layer
231 which is against the base layer 230. The base layer 230 is made
from the blocks 220 by orienting the blocks 220 with the fifth face
30 against the ground. The blocks 220 in the first section 226a
have their first faces 22 co-planar with each other, while the
blocks 220 in the second wall section 226b are oriented so that
their first faces 22 are 90.degree. to the first faces 22 of the
blocks 220 in the first section 226a.
[0132] The blocks 220 in the first layer 231 are oriented upside
down from the blocks in the base layer 230, so that the sixth face
32 and remainder section 38 of the blocks 220 in the first layer
231 mateably engage and are received by the remainder section 38 of
the blocks 220 in the base layer 230.
[0133] At the corner 228, the sixth face 32 of the block 220a in
the first layer 231 is engaged against the sixth face 32 of the
block 220b in the base layer 230. The block 220b is in the wall
construction section 226b, while the block 220a is in the wall
construction section 226a. As such they are perpendicular to each
other.
[0134] F. Example Block, FIG. 23
[0135] FIG. 23 illustrates another embodiment of the block, shown
here as block 320. The same reference numerals are used for the
same parts, although it should be understood that the outer
perimeter of block 320 has a different shape from that of the block
20 of FIG. 1, block 20' of FIG. 7, block 20'', and block 220, as
further described.
[0136] In this embodiment, the remainder section 38 includes four
planar faces 361, 362, 363, 364. In FIG. 23, it can be seen how the
remainder/irregular section 38 has first cavity 48 with a perimeter
shape of a triangle 370, while the first projection 54 also
includes a triangle perimeter shape 371.
[0137] The planar faces 361, 362 are angled relative to each other
to form the first cavity 48. The planar faces 362, 363 form a
triangular perimeter shape of the first projection 54. Extending
from a base of the first projection 54, at an end of the face 363
is the planar face 364 extending to the fourth face 28. The planar
face 364 is generally parallel to the fifth (bottom) face 30. In
preferred embodiments, the planar face 364 is co-planar with the
first section 36 of the sixth (upper) face 32.
[0138] In this embodiment, the first section 36 has a length 40
from the third face 36 to the remainder section 38 at least as long
as the thickness 34 of the block 320. In the example shown in this
embodiment, the length 40 of the first section 36 is greater than
the thickness 34 of the block 320.
[0139] FIG. 23 shows a wall construction 378, including wall
section 378a and wall section 378b joined at a corner 380 assembled
from the blocks 320. In the example shown in FIG. 23, the wall
construction 378 has two layers or courses of blocks 320. It can be
seen how the base course 381 is laid with the fifth/bottom face 30
against the ground surface, and the first course 382 is assembled
on top of the base course 381 with the sixth face 32 pointed
downwardly to mateably engage with the base course 381. The
remainder sections 38 of the blocks 320 mateably engage with each
other.
[0140] At the corner 380, one of the blocks 320b at the corner 380
is in the base course in part of the wall construction 378b and is
perpendicular to the wall construction 378a. The block 320b has its
sixth face 32 engaged against the sixth face 32 of block 320a in
the first course 382 in the wall construction 378a.
[0141] G. Example Methods
[0142] A variety of structures can be constructed from the blocks
described herein with methods as generally described above. The
methods generally include laying out the base course of the blocks,
and arranging a first course on top of the base course in such a
way that the first course is oriented so that the remainder section
of the first course is against and mateably engaged with the
remainder section of the base course. Corners can be constructed
due to the length of the first section of the sixth face being as
least as long as the thickness of the block as defined by the
distance between the front and back faces. The result of this
geometry is that a corner is made by the sixth face of one of the
blocks in the first course and at the end of a wall section
perpendicular to a first wall section is engaged against the sixth
face of one of the blocks at the corner section and of the wall
perpendicular to it in the base layer.
[0143] The above represents example principles. Many embodiments
can be made using these principles.
